87 YJ 4.2 factory splices used duct tape?!?!?!?

I'm rifling through yards upon yards of wire throughout the factory looms in my 87 yj 4.2 and have noticed several instances of splices being covered in duct tape. These splices are secured within some flex loom and appears somewhat factory, I do however, not recall ever knowing any factories that built their cars with duct tape. Has this wiring been gone through prior my ownership? Anyone? Anyone?

Mossy had tons of that going on (definitely NOT factory [img]images/graemlins/grin.gif[/img]). I have since removed all the POs electrical "upgrades". When I was finished, I had enough wirenuts to fill a coffee can [img]images/graemlins/crazy.gif[/img].

So does an 89 Chevy with fuel injection, as I am pulling apart one of their harnesses. Crimp splices, soldered as well, and wrapped in what looks suspiciously like duct tape! Not sure if they crimped then soldered, or solder tinned the wires, then crimped on the splice. Seems to have held up well. Same with my 84 CJ, splices galore.

There's a reason that realy could be disputed, I suppose.

Duct tape actualy has very good insulating properties and we all know it holds up well. Though it may be a pain to remove, it has better adhession than standard E-tape and can actually keep out the elements better.

It just looks bad but works well.

1. If it quacks like duct tape.
2. And it walks like duct tape.
3. It must be duct tape.
4. But it AIN'T duct tape.
5. It's a "look-alike."
6. It is really Harness Wrapping Tape.
7. The stuff's:
a. Got really aggressive glue so it won't unravel.
b. Good Cloth-like covering to keep elements out.
c. Strong as a bull to bundle wires tightly when wrapping.
d. Often it's a glass-cloth coated tape.
e. It's also a fire retardant, due the impregnation of the cloth coating.
8. So you can see... it's really a little more than "duct tape."
9. But it still is a cloth tape... and darned good stuff at that...
10. Were I to replace it I'd:
a. Use dental floss or plastic tie-wraps to harness wrap the wiring.
b. Use plasic spirial wrap or plastic tubing to encase the wiring.
